Challenge

This homeowner in Chantilly, VA contacted us with growing concerns about the structural integrity of their home. Over time, they had noticed worsening stair-step cracks in the foundation walls, shifting bricks, and uneven concrete slabs around the property. These are classic signs of foundation settlement, which is often caused by unstable soil conditions, hydrostatic pressure, and inadequate drainage systems—all of which are common issues in the Northern Virginia region.

Upon inspection, it was clear the foundation was no longer stable. The cracks were increasing in size, interior walls were showing signs of separation, and parts of the structure were visibly uneven. Compounding the issue was a poorly managed water runoff system, which was directing rainwater and groundwater directly toward the home's foundation. This resulted in excess moisture around the perimeter, causing soil erosion and accelerating the settling process.

Without immediate intervention, the homeowner risked severe structural damage, expensive future repairs, and a significant drop in property value. The homeowner was looking for a permanent foundation repair solution in Chantilly, VA that would both stabilize their home and prevent further water-related foundation problems.

Solution

To fix the foundation issues at this Chantilly, VA home, our expert team designed a complete foundation repair plan to stabilize the structure and prevent future damage.

We began by installing 3 Helical Piers under the home’s foundation. These steel piers go deep into stable soil and provide strong support to lift and hold the settling areas in place. Helical piers are one of the most effective ways to stop a foundation from sinking.

Next, we installed 9 GeoLock® Wall Anchors along the foundation walls. These anchors help straighten walls that are bowing or pushing inward and keep them from moving any further. This is a common solution for homes in Northern Virginia with soil pressure issues.

To seal and protect the home from water intrusion, we used NexusPro® Crack Repair Sealant on all visible cracks and joints in the foundation. This flexible, long-lasting material prevents water from getting into the home and causing further damage.

During the process, we had to dig trenches to install the wall anchors, so we replaced the concrete afterward to restore the property’s clean and finished look.

Finally, we installed a yard drainage system designed to redirect rainwater away from the foundation walls. Managing water flow around the home is key to preventing soil erosion and keeping the foundation secure over time.

The result? A stable, level, and protected foundation—and a very happy homeowner in Chantilly, VA. With this combination of solutions, the home is now better protected against future foundation settlement and structural problems.

The NV Waterproofing crew just finished pulling up the home in Chantilly and is now prepping the site to begin foundation repairs for lasting stability.

Helical piers were installed, the wall sealed, and the area refilled with dirt and grass seed, preparing the site for the installation of wall anchors.

Anchors installation process

We installed 9 GeoLock® Wall Anchors to stabilize the foundation walls and prevent further bowing or inward movement. These anchors are designed to stop wall failure by using the strength of stable soil outside the home. This proven solution is ideal for homes in Chantilly, VA where pressure from expanding soil can cause serious foundation wall issues. Now, the walls are secure, and the home is structurally sound.
